Network Centric Operations
Operations enabled by
– Information Networks • Technology-enabled infrastructure
and
– Social Networks• People working in collaboration

NCO Requirements
Net-Centric Operations requires People, Processes, and Technology that work together enabling timely and trusted: – Access to information, – Sharing of information, and – Collaboration among those involved.
NCO is more about crossing organizational, asset and domain boundaries– Enabled by the Net– Expected by the emerging global culture

NCOIC & Interoperability
Building Blocks Functional Team: Identifies elements that help enable interoperability for interested stakeholders.
Net-Centric Assessment Functional Team: Develops tools for use by systems engineers to determine the level of Net-Centricity that has been achieved in systems.
NIF Architecture Concepts Functional Team: Develops enabling guidance consisting of architectural principles, and NCO patterns

SCOPE
Systems, Capabilities, Operations, Programs, and Enterprises (SCOPE) Model for Interoperability
Purpose - Describe the degree to which a set of Systems supports a Capability, Operation, Program or Enterprise (SCOPE) over a network
Provides a means to characterize interoperability requirements for network centric systems
Designed to characterize interoperability-relevant aspects of a system or capability in terms of a set of dimensions.
– Each dimension represents a specific aspect of a system/capability or its surrounding environment/context, and enables assessment of that aspect within a range of possible values (discrete or continuous) that is unique to that dimension

SIF WG Objectives
Develop a comprehensive understanding of the problems of semantic interoperability in a NCO environment
Define a semantic interoperability framework (SIF) where the scope and role of each problem can be illustrated and where problem specific architectural pattern solutions can be integrated (Services, Situational, and Knowledge Sharing domains)
Investigate, describe, and provide guidance in the use of semantic technologies and standards that supports mutually consistent understanding of shared information
Develop NCO Capability Specific Semantic Interoperability Patterns
Semantic Interoperability Concept Map
Develop Semantic Interaction Model
– Based on speech acts
– Characterizing intention (sufficient for NCO)

NCOICSemantic Interoperability Principles
Interoperability between systems and agents is – Purposeful – Informed by goals, – Operating in contexts – Sharing domain knowledge (whether explicit or implied).
Goals guide selection of intentions and execution of actions Communications occur within a few universal intentional
categories (Speech Acts – request knowledge, commit to action, request action, … )
Context constrains relevant domain knowledge for a situation
Useful Knowledge is organized in semantic domain models

NCOIC Terms
Network-Centric:– Related to systems and patterns of behavior that are influenced
significantly or enabled by current and emergent networks and network technologies. Often these center around IP-based internetworking, but the term is sometimes used to include any type of enabling network.
Network-Centric Operations (NCO):– An information superiority-enabled concept of operations that
generates increased combat power by networking sensors, decision makers, and shooters to achieve shared awareness, increased speed of command, higher tempo of operations, greater lethality, increased survivability and a greater degree of self-synchronization.
Net-Centricity Necessarily Requires Interoperability
